Reiwa Black Lamé Miyuki Sapphire Medaka – 令和黒ラメ幹之サファイアメダカ

Reiwa Kuro Rame Miyuki Sapphire Medaka – 令和黒ラメ幹之サファイアメダカ A starlit shimmer on midnight scales with golden-finned elegance Physical CharacteristicsThe Reiwa Kuro Rame Miyuki Sapphire Medaka is a breathtaking ornamental medaka variety that radiates brilliance from deep, jet-black scales adorned with dazzling blue lamé. This refined strain captures both intensity and refinement, shimmering like a night sky sprinkled with stardust. Origin and Development This variety was developed by integrating the Reiwa gene into the Kuro Rame Miyuki Sapphire lineage to enhance the pigmentation of the fins (particularly yellow expression) while maintaining the striking lamé and dark body coloration. The challenge lies in achieving both dense lamé and visible hirebi in a semi-transparent strain—something previously rare but now more possible thanks to careful gene integration by Seiraku-an. Breeding Notes ConclusionThe Reiwa Kuro Rame Miyuki Sapphire Medaka represents a new era in ornamental medaka breeding—blending the elegance of lamé with the innovation of genetic enhancement. Its dark body and glowing highlights make it one of the most visually dynamic medaka strains to emerge in recent years. For breeders and collectors alike, this fish is a testament to what’s possible when science meets beauty. Sources / 出典:
